使用高氨氮废水灌溉农田,常导致农作物的严重危害。但在实践中,当发现作物已经遭受危害时,而土壤中氨氮含量却往往很低,从而给污染事故仲裁带来困感。为探明这一问题,作者对土壤中氨氮的转化进行了模拟研究。1 材料与方法1.1 土壤来源 供试土壤来自太原北郊的石灰性褐土 Irrigation of farmland with high ammonia-nitrogen wastewater often causes serious damage to crops. However, in practice, when the crop is found to have been endangered, the ammonia nitrogen content of the soil tends to be very low, which can cause difficulties for the arbitration of pollution accidents. In order to prove this problem, the author has carried on the simulation research to the ammonia nitrogen transformation in the soil. 1 Materials and methods 1.1 Soil source Soil from the calcareous cinnamon soil in the northern suburbs of Taiyuan
